Ruminations #5 | Heat stress in dairy cattle: strategies to optimize performance and the role of Bacillus probiotics
June 11, 2026 16:00 Europe/Copenhagen
Heat stress remains one of the biggest seasonal challenges impacting dairy productivity, feed efficiency, herd health, and farm profitability. As temperatures rise, dairy cows experience reduced feed intake, impaired rumen function, lower milk yield, and increased physiological stress — all of which can compromise health, performance and profitability. A true biological challenge.
Join this webinar to explore practical nutritional and management strategies that help dairy producers support cow resilience and maintain productivity during periods of heat stress. We will discuss the importance of gut health, nutrient utilization, feed efficiency, and microbial balance in supporting dairy cows under challenging environmental conditions.
The session will also highlight emerging research on Bacillus probiotics, and their role in supporting digestive function, feed efficiency, and dairy cow performance. Research has demonstrated improvements in milk production efficiency, nutrient digestibility, and overall herd productivity when Bacillus probiotics are included in dairy feeding programs.
Key topics include:
The impact of heat stress on dairy cow physiology and productivity
Nutritional and management approaches to support resilience
Gut health and feed efficiency under heat stress conditions
Research insights on Bacillus probiotics in dairy production systems
Designed for nutritionists, veterinarians, dairy consultants, and progressive dairy producers, this webinar provides science-backed insights and practical tools to help optimize herd performance during heat stress periods.
